 聚丙烯基磷酸酯的制备及其阻燃黄麻织物 的研究# 王灿灿，魏丽乔** 5 10 （太原理工大学新材料界面科学与工程教育部重点实验室，太原 030024） 摘要：以三氯氧磷、丙烯醇和甲醇为原料合成了一种聚丙烯基磷酸酯阻燃剂，并得出了其合 成的较适宜条件：丙烯基二甲基磷酸酯单体浓度 75%，KPS 浓度 4%，辐照功率 550W，微 波辐照时间 6min。将合成的阻燃剂喷涂在黄麻织物表面并制备出阻燃黄麻织物。利用场发 射扫描电子显微镜(FE-SEM)对阻燃黄麻织物进行表面形貌分析，采用热重 (TG)和氧指数测 试仪对阻燃黄麻的热性能和燃烧性能进行分析。结果表明，经过阻燃处理后，黄麻织物的残 渣率和极限氧指数均明显提高，由易燃纤维变为难燃纤维，具有良好的阻燃性能。 关键词：轻工业、手工业；黄麻织物；阻燃；磷酸酯 中图分类号：TS126 15 The Preparation of Polypropylene Phosphate for Flame Retardent and Its Application in Jute Fabric WANG Cancan1, WEI Liqiao2 (1.

The optimal reaction conditions was as follows: the dosage of monomer of allyl dimethyl phosphate is 75%(owf), the dosage of KPS 4%(owm), microwave power 550W, couring 6min. The paper adopts surface coating flame retardant treatment on jute fabric. The surface morphology of flame retardant jute fabric was characterized by field emission-scanning electron microscopy (FE-SEM). Flammability and thermal behaviors of flame retardant jute fabric were investigated by Limiting Oxygen Index (LOI) and thermogravimetry (TG). The results show that the residue rate and LOI of flame retardant jute fabric were all increased dramatical, which transformed the inflammable fibers into flame retardant ones with remarkable flame retardant properties.
